To all whom it may concern:

Be it known that l, FRANK BEEMER, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Gearing for Motor-Vehicles, of which the following is a specification.

Objects of the present invention are to provide a compact, strong, ellicient and durable construction and arrangement of the transmission and speed changing parts; to provide for arranging and supporting the revoluble parts in such manner that they are held in proper mechanical alincment; to provide for ready access to and removal of the parts of the'di Eterenlial and speed changing mechanisms; in provide for efficiently and satisfactorily supporting the differential and speed changing mechanisms in roXimity with the driven axle and with eac 1 other; to provide convenient and reliable'means for adjusting the bevel gears of the differential and speed changing mechanisms in respect to each other so that proper'meshing thereof can be secured and maintainml; to provide a single structure comprising within itself all of the mechanism between the engine shaft and the wheels and which structure can be sold as a complete, article and readilyassembled with other parts 'to make a complete motor vehicle: and another object of the invention is to simplify themeans for supporting the parts which'are pivotally connected with the rear axle.

To these and other ends hereinafter set forth, the invention comprises the improvements to be presently described and finally claimed.

The nature, characteristic features and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof and in which Figure 1, is a top or plan view, partly in section, illustrating, gearing embodying featuresof the imention. Fig. 2, is a sectional view taken on the line 2--'2, of Fig. 1, and, showing means for maintaining certain of'the parts in adjusted position. Fig. 3, is a rear view, partly in section, illustrating portions of the gearing embodying features of the invention. Fig. 4, is an elevational view,

artly in section, illustrating the gearing. l ig. 5, is a horizontal sectional view illus-- and 3, and a forwardly extending housing 4,

provided with a forwardly extending tubular support 5, arranged at right angles with and centrally of the lateral extensions 2 and 3. Within the. spherical casing there are crosswise ranging ribs 6, which serve to strengthen it,

7, is a detachable cover for an opening in the rear ofthe casing-and through which the mechanism to be described can be reached and if necessary removed.

8, is a detachable cover for an openingin the'housing 4, through which access may be had to the speed'ehanging mechanism.

, Within the casing 1, there are formed ribs or webs that carry two-part bearings or hearing supports 9, and there is also'a'standard or bracket 10, which constitutes a bearing or hearing support. The hubs 11, of the casing or housing" of the differential mechanism are arranged in these two-part bearings 9. An annular ball bearing, 12, is shown interposed between the hubs and the beari'ngsupports. Collars 13 and 14, each having cam faced ends are arranged on the hubs of the housing of the differential mech anism. Upon one of the collars 13, is arranged an end thrust ball bearing 16, so that this hearing is interposed between the support 9, and a flange 15, on the collar. The

other collar 14, abuts on the housing of the trating differential mechanism.- Fig. 6, is a take into these teeth. By turning the pairs of eolla1s 13 and 14, in respect to each other it is possible to shift the housing of the differential gneehaiiism which carries the bevel wheel 17, in one direction or the other between the supports This adjustment is effected by the cam faces 18 and 19, and when completed the dogs by engaging the teeth )rcvent further relative movement of the collars and thus positively maintain the adjustment. The adjustment may be readi ly made and it will be understood that its purpose is to bring the bevel gear 17, into proper mesh with the bevel gear 20. Screws 21, taking into suitably tapped openings in the supports 9, are shown for detachably holding the cover 7. The wheels 22, are arranged-to run on annular bearings 23, interposed between them and the lateral extensions 2 and 3, or continuations thereof.

24, is band brake mechanism.

25, are the live axles which are connected with the hubs as by means of hub clutches 26, and have their squared inner ends ar ranged in corresponding openings in the two larger wheels 27 and2-8, of the differential mechanism. Thesewheels 27 and 28, mesh with smaller pinions 29, journaled upon studs arranged upon alternate sides of the housing of the differential mechanism. These pinions intermesh with each other in pairs but each one of each pair engages wit-h only one of the large wheels 27 and 28. The front end of the tubular support 5, is provided with a yoke 30,'which is pivotally or lnovably connected with and supported by a bracket 31, that can be attached to a suitable portion of the chassis.

32, is'the engine shaft or a continuation thereof, and it is journaled for revolution in an appropriate manner and is connected with the universal joint 33-3.

34, is a drive shaft. It is connected at one end with the universal joint and at the other end is fitted with a pocket and with a gear 35. This drive shaft is arranged through the .tubular support 5, which at its ends is fitted with annular bearings 36, and at its front end with a thrust bearing 37. The last named bearings are arranged in recesses in the tubular support and are held to place therein by screw rings 38 and 39. Tl'tere is a shoulder on the drive shaft which abuts on the end thrust bearing 37. By screwing the partsiiS and 39', it is possible to shift the drive shaft 34 endwise. for a )ur pose which willbe hereinafter described. Within the forwardly extending housin 4, there is revolubly mounted by means of annular bearings 40, a shaft 41, upon which are carried the speed gears 42, 43, 44-, and 45. By removing the cover 46, access mav be had to the adjusting collars a, of the shaft 41.

There is a speed shaft 47, one end of which is fast to the bevel gear 20, and the other end of which is sup )orted by a roller bearing and a ball arranged in the end of the drive shaft 34. 'lhis shaft 47, is squared and on it are slidably mounted the speed gears 48 and 49, which can be shifted by means of the forks 5t) and 51, the shanks of which are. sleeved together and connected with operating links 52, and 53. There is a backing gear wheel 54, journaled on a shaft, the ends of which are supported by brackets projectinginward from the wall of the housing 4. 'lhe. gear wheel 35, drives all tlie'whecls on the co u tcr-shal't 4]. The wheel 45, drives the backwheel 54 when it is necessary to back the vehiole and with the ear wheel 44, for the first.

forward speed. T 1e gear wheel 45) meshes with the gear wheel 43 for the second s )eed ahead. None of these wheels are slufted into engagement with another wheel and then past it. Any speed can be obtained without going through other speeds. 'lhe mechanism is selective in the sense that any 'speed can be obtained without the necessity of passing through the other speeds. ,For example, it is possible to go from the highest. to the lowest speed without going through the intervening speedsi There is a bushing 55, which is screwed into a tapped opening arranged within the spherical casing 1. Externally this bushing is provided with teeth that may be engaged by a dog 56, Fig. 2, so that the bushing may be screwed back and forth and then locked to place by the dog.

Internally this bushing is rovidcd with a flange 57 arranged intermet iate of its ends. To one side of the flange is arranged an annular ball bearing 58 and a ball thrust bearing 5t). To the other side of the flange is arranged an annular ball bearing 60, and jam nuts or locking collars 61, that are secured in the present instance by a screw thread to the. speed shaft 57. The bushing 55, may be screwed in one direction or the other. It carries with it the. beveled gear 20, so that the beveled gear may in this way be adjusted in respect to the bevel gear 17, thus insuring )roper meshing or running of the two gears. lhis adjustment may be comptmsated for by suitably shifting the rings 35 and 38, which causes the drive shaft 34, to maintain its pro er relation in respect to thespeed shaft 47.
